Cognitive Approach to explaining depression

The cognitive approach explains depression in terms of faulty thinking patterns - the idea that how we interpret events shapes how we feel.


Beck’s Cognitive Theory of Depression:

Developed by Aaron Beck.


Negative Triad:

Beck suggested depressed individuals have a negative schema, leading to a traid of negative thoughts:

1 - Negative view of the self

        e.g. “I’m worthless”

2 - Negative view of the world

        e.g. “Everything is against me”

3 - Negative view of the future

        e.g. “Things will never get better”


Faulty Information Processing:

Depressed people also show thinking errors, such as:

  • Overgeneralisation (one bad event = everything is bad)

  • Catastrophising (expecting the worst)

  • Selective abstraction (focusing only of negatives)


Role of Schemas:

  • Schemas are mental frameworks developed for experience (often childhood)

  • Negative schemas bias how information is interpreted → maintaining depression


Ellis’s ABC Model:

Proposed by Albert Ellis.

ABC Components

A - Activating event                            Something happens (e.g. failing a test)

B - Beliefs                                           Interpretation of the event

C - Consequences                             Emotional/behavioural outcome


Key Idea:

Its not the event (A) that causes depression, but the belief (B) about it.


Irrational Beliefs:

Ellis identified common irrational beliefs:

  • “I must succeed at everything”

  • “Everyone must like me”

  • “Life should always be fair”

When these are violated → negative emotional consequences (C), such as depression


Summary:

Beck: Depression comes from negative schemas → negative traid + biases

Ellis: Depression comes from irrational beliefs about events (ABC Model)


Evaluation (AO3 points)

Strengths:

  1. Strong Research Support

  • Studies show depressed individuals do have negative thinking patterns (supporting Beck’s negative triad).

  • For example, research using questionnaires found depressed ppts interpreted situations more negatively.

→ Supports the idea that cognition plays a key role in depression.


  1. Practical Applications (CBT)

  • The approach led to Cognitive Behavioual Therapy (CBT).

  • CBT challenges negative thoughts and replaces them with more realistic ones.

  • Proven to be effective treating depression.

→ This gives the theory real-world value.


  1. Recognises Role of Thought Processes

  • Unlike behaviourist explanations, it focuses on internal mental processes.

  • Provides a more complete explanation of depression.


Weaknesses

  1. Cause vs Effect Issue

  • Negative thinking may be a symptom of depression, not the cause.

  • It’s unclear whether faulty cognition comes before or after depression.

→ Weakens the claim that cognition alone explains depression.


  1. Ignores other factors

  • Biological factors (e.g. genetics, neurotransmitters)

  • Social factors (life events, trauma)

→ Depression is likely multi-factoral, so this is reductionist.


  1. Not All Depression Involves Faulty Thinking

  • Some people have realistic negative views (e.g. difficult life circumstances).

  • Known as depressive realism.

→ Suggests the model doesn’t apply to everyone.


The cogntive approach is well-supported and useful in treatment, but is limited by reductionism and issues with causality.
